The Strobella is a small shoot-through umbrella that you mount to your flash unit using a velcro elastic band. The website states that it “doesn’t just softens the shadows but can reduces them significantly.” Hmm…
David Hobby over at Strobist is a fan:
This one is very hard to post with a straight face [...] I would only say that any umbrella of this size should rightfully have a stiff, fruity drink under it — with a tropical sunset as a backdrop.
The Strobella costs about $13 bucks if you live in Europe, and about $15 if you’re elsewhere. Yay for random camera attachments that will give you weird looks!
